I didn´t intend to overwrite any files: /raid certainly wasn´t in use
at the time.

That is a very good question indeed..

The folder I was trying to restore was a harmless one in /raid that
should have nothing to do with the rest of the system as far as I
know... It's just the place I store the /home of a completely
different system.

rsync is not really an alternative for me because at the time the
backup runs usually only the server is running, not the client (my
desktop).

Yes it should back up /etc and /var of localhost (the server). But
these weren´t selected to be restored.

I am a little bit further: I found that all applications depending on
Perl are broken, and I found this in Backuppc log:

   2011-12-08 20:17:37 Started restore on localhost (pid=11576)
   2011-12-08 19:28:11 localhost: Can't locate Carp/Heavy.pm in @INC

/usr/share/perl/5.10/Carp.pm line 39.

But I think it exists (/usr/share/perl/5.10.1 is symlinked to
/usr/share/perl/5.10):

   # locate Heavy.pm
   /usr/share/perl/5.10.1/Carp/Heavy.pm
   /usr/share/perl/5.10.1/Exporter/Heavy.pm

Backuppc is running as user backuppc which is in sudoers to run tar as root.

I am starting to suspect that my Perl is messed up, because everything
that uses it is broken. I've tried to re-install its packages but no
luck yet.
